ISSUES IN COLLECTING DATA

ISSUES IN COLLECTING DATA

1. TRIANGULATION

   • data triangulation
     • For example, data related to the time and social situations collected on different occasions. 
     • variety of sampling strategies
   • investigator triangualtion
     • contributions of more than one observer
       • To give the research study more reliablity.
   • Methodological triangulation
     • methods to collect data
       • Observation, analysis of transcripts and self-report surveys.
   • Theoretical Triangualtion
     • data analysis with more than one perspective

2. RELIABILITY

   • Consistency and replicability
     • Internal reliability
       • consistency of data collection, analysis and interpretation.
     • external reliability
       • researchers possibilities to reproduce a study
     • intra-observer agreement
       • categorising consistently the same data after a lapse

3. VALIDITY

   • The procedure accurately represents the content it is supposed to measure.
     • The results of an experimental study can be reliably and unambiguously related to the implemented treatment. 
     • Construct Validity
       • A verifiable and measured construct
       • Describe the characteristics of the construct
       • A belief or theoretical label
         • It may mean different things to different people. 
     • Criterion Related Validity
       • Researchers are concerned with the fact that the treatment is implemented in a given research study and this treatment is identifiably different from whatever it is compared with. 
       • A valid measure

4. GENERALISABILITY

   • findings of a study can be generalised or applied to other situations
     • population
       • The entire group of subjects of interest
     • sample
       • The smaller group studied by the resesaarcher
     • standar deviation
       • statistic measure
         • indicates the variety of a group of scores
